+/* SYNC STREAMS
+   ============
+
+   We stream human-readable tokens to stdout, and binary data (fonts,
+   bitmaps) to g_binary_out. Another process reads from those pipes, and
+   there lies the rub: things can deadlock, if the two involved
+   processes access the pipes in different order. At any point in
+   time, both processes must access the same pipe. To ensure this,
+   data must be flushed to the OS before writing to a different pipe,
+   otherwise not-yet-written data will leave the reading process
+   waiting on the wrong pipe.
